Which Portuguese phrase is the official name commonly used for Portugal’s May 1 workers’ holiday?

Portugal’s May 1 workers’ holiday is commonly called Dia do Trabalhador.

The Portuguese phrase means “Workers’ Day.” It is Portugal’s observance of International Workers’ Day, and public events commonly include union marches, political speeches, and gatherings centered on labor rights and working conditions. The holiday is observed nationwide on May 1.

Portugal’s modern history gives the date additional political meaning. After the Carnation Revolution of April 1974 ended the Estado Novo dictatorship, the first May Day celebration that year became a huge public demonstration of the country’s new political freedoms. That association helped make May 1 particularly prominent in Portuguese civic life.

Dia do Trabalhador is different from Portugal Day, celebrated on June 10, and Freedom Day, celebrated on April 25. Those holidays commemorate distinct national events.
